I tried baking soda in leather bags but not LV to remove mothball smell. Instead of placing a pack of baking soda inside the bag, I dissolved the powder in water, then clean the interior by using a damp cloths soaked in the mixture, then air out the bag. You might want to put the bag in the sun for the beginning, but avoid bright sunlight. Again, I have not tried this in LVs so please handle with care if you wanna give it a try. Or, just starting to use your bag if the smell is not that strong, it will get better over the time.
